Propolis Cognitive Error Autopsy

Official Correct Choice:
Option B: Lysosomes
Concept: Compartmentalization of destructive enzymes is crucial to prevent the cell from digesting itself.

Solution: Lysosomes are single-membrane-bound spherical sacs that contain a cocktail of powerful acid hydrolases (hydrolytic enzymes) used to digest macromolecules, old organelles, and engulfed pathogens.

Distractor Autopsy: Mitochondria and chloroplasts are double-membrane structures involved in energy conversion. Golgi bodies are stacks of flattened sacs (cisternae), not spherical sacs.

Quality & Fidelity Assurance: Every question on BeambePrep is rigorously curated against the official PMDC syllabus with zero filler, zero out-of-syllabus content, and zero typos. When an authentic past paper originally contained a historical mistake or ambiguity from the examining board (such as UHS or NUMS), BeambePrep faithfully reflects the original paper while detailing the nuance and scientific consensus in the autopsy above.
